FlyingZC opened a new issue, #27015: URL: https://github.com/apache/shardingsphere/issues/27015
# Background Hi community, This issue is for #26878. ShardingSphere parser engine helps users parse a SQL to get the AST (Abstract Syntax Tree) and visit this tree to get SQLStatement (Java Object). Currently, we are planning to enhance the support for Oracle SQL parsing in ShardingSphere. More details: https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/ # Task This issue is to support more oracle sql parse, as follows: ```sql AUDIT SELECT, INSERT, DELETE ON jward.dept BY ACCESS WHENEVER SUCCESSFUL; ``` ```sql AUDIT SELECT TABLE, UPDATE TABLE BY hr, oe; ``` ```sql AUDIT SESSION BY jward, jsmith BY ACCESS; ``` ```sql BINARY_DOUBLE BINARY_FLOAT BFILE BLOB CLOB CHARACTER SET ANY_CS DATE DSINTERVAL_UNCONSTRAINED NUMBER TIME_UNCONSTRAINED TIME_TZ_UNCONSTRAINED TIMESTAMP_LTZ_UNCONSTRAINED TIMESTAMP_TZ_UNCONSTRAINED TIMESTAMP_UNCONSTRAINED UROWID YMINTERVAL_UNCONSTRAINED user-defined object types collections (VARRAYs and nested tables) REFs Opaque types ``` ```sql CANCEL ALTER DATABASE OPEN READ ONLY; ``` # Process 1. First confirm that this is a correct oracle sql syntax, if not please ignore; 2. Compare SQL definitions in Oficial SQL Doc and ShardingSphere SQL Doc; 3. If there is any difference in ShardingSphere SQL Doc, please correct them by referring to the Official SQL Doc; 4. Run mvn install the current_file_module; 5. Check whether there are any exceptions. If indeed, please fix them. (Especially xxxVisitor.class); 6. Add new corresponding SQL case in SQL Cases and expected parsed result in Expected Statment XML; 7. Run SQLParserParameterizedTest to make sure no exceptions. # Relevant Skills 1. Master JAVA language 2. Have a basic understanding of Antlr `g4` file 3. Be familiar with Oracle SQLs -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
